Don't wait until your dashboard warning light is on to inspect your engine control computer (ECC). It's important to recognize symptoms of a defective ECC, so you can replace your electrical control unit with a new one.

If your ride fails to start for no apparent reason, you should check to see if there's something wrong with your starter, battery and other electrical components. If your vehicle still doesn't run, it's possible that you have an issue with your ECC. Sudden stopping or jerking problems that are associated with transmission matters or difficulties shifting gears in an automatic transmission are clear indicators that your ECC is malfunctioning. An unexplained drop in fuel economy is also a clear sign it's time to swap out your ECC.

AutoZone has products that are designed exclusively for your make and model when it's time to replace your engine control computer. So, whether you're looking for an ECM for F150 trucks or a Honda Accord engine control module, you're certain to find the perfect match for your ride when you check out our wide variety. Stop by your local store and ask our staff for advice about replacing your ECC or order online.
